AbstractThe interfacial interaction between the fiber and matrix is the most important factor which influences the performance of the carbon fiber-epoxy composites. In this study, the graphitic surface of the carbon fibers was modified with graphene oxide nanomaterials by using a spray coating technique which is an easy, cheap, and quick method. The carbon fiber-reinforced epoxy matrix composites were prepared by hand layup technique using neat carbon fibers and 0.5, 1 and 2% by weight graphene oxide (GO) modified carbon fibers. As a result of SEM analysis, it was observed that GO particles were homogeneously coated on the surface of the carbon fibers. Furthermore, Young's modulus increased from 35.14 to 43.40 GPa, tensile strength increased from 436 to 672 MPa, and the elongation at break was maintained around 2% even in only 2% GO addition.

In this study, we present a novel approach to graft a large number of poly(glycidyl methacrylate) (PGMA) chains onto the carbon fiber (CF) surface through reversible addition-fragmentation chain transfer (RAFT) polymerization. Characterization results of FT-IR, XPS and TGA demonstrated that PGMA was covalently combined with carbon fibers. The CF/epoxy composites were obtained by addition of pristine CF and CF functionalized with poly(glycidyl methacrylate) (CF-PGMA) into epoxy resin. Experiment results revealed that the grafting of PGMA chains on the CF surface could increase significantly roughness and number of active groups of CF, which enhanced interface and mechanical properties of the composites. The compression strength, tensile strength, flexural strength and interfacial shear strength (IFSS) of CF-PGMA/epoxy composites are enhanced by at least 63.1%, 37.9% 55.6% and 122.5%, respectively, compared to pristine carbon fiber/epoxy composites. This enhancement indicates that surface modification of the carbon fibers by RAFT technique is a potential method to preparing CF-reinforced polymer matrix composites with excellent mechanical properties.
